Title: Method and apparatus for producing an audio magnetic tape recording at high speed from a preselected music libray
IPC: G11B27/031
Filed: 1988-02-19
Abstract: The present invention relates to a novel 
method and apparatus for taking an analog audio 
signal, converting the signal into a digital audio 
signal, and thereafter converting the digital audio 
signal into a standard bandwidth video signal and 
thereby substantially compressing it. In this 
format, it can be placed onto a master video tape 
from which it can be transferred to a video disk. 
The present invention further comprises a method 
and apparatus from which a selected number of 
recordings on the video disk can be retrieved by 
playing the video disc in still frame mode to 
create an analog video signal, converting the 
analog video signal into a string of digital 
values, converting the digital audio stream into an 
analog audio signal and thereafter recording the 
audio signal onto an audio tape at high speed. 
This method and apparatus is used as the central 
technology in a consumer electronic music center 
wherein a consumer can randomly select a given 
number of song selected from a music library and 
thereafter create his or her own customized audio 
tape in a matter of minutes.

Title: Web processing with two mated rolls
IPC: B31F1/18
Filed: 1989-06-21
Abstract: A machine and process for a web of material 
employing two side-by-side sets of spaced apart driven 
disks adapted to rotate respectively in opposite 
directions about two spaced apart parallel axes, the 
axes being sufficiently close that peripheral margins of 
the disks of one set run between the peripheral margins 
of the disks of the other set in a mated relationship, 
the sets of disks mutually defining a series of web 
driving regions spaced apart in a direction parallel 
with the axes, with successive web driving regions, 
offset from one another, open channels between said 
disks providing, with the driving regions, a width-wise 
continuous, non-linear cross-section corridor through 
which the web passes, the driving regions adapted to 
impart to a web led lengthwise into the corridor, 
crosswise tension in the web, pulling the web about the 
edges of the disks, the tension enabling the disks to 
apply forward driving force to the web and retarding 
means closely disposed to the driving regions located to 
apply retarding forces on the web in the region of the 
corridor, the retarding forces opposing the driving 
forces to produce immediate, continual longitudinal 
shortening of the web. The machine and process is 
especially useful in softening strong sheets as by 
permanently loosening bonds between components of the 
web.

Abstract: In an image forming apparatus for forming an ordinary 
copy or a tonality image for an original image for a 
printing press, original image data is divided into a 
predetermined area, and pixel density within the area is 
subjected to a density conversion in accordance with 
screen half-toning information which will increase 
density information toward the approximate center of 
these pixels, by way of example. The original image data 
or the density-converted image data is converted into a 
binary-coded signal conforming to the density, and an 
output image is formed in accordance therewith. 
Preferably, plural types of non-linear correction tables 
are provided and a tone-conversion is performed selecting 
a correction table for every pixel or every line of the 
density-converted image data. Preferably, the original 
image data is binary coded by a pattern signal having a 
long period, and the density-converted image data is 
binary coded by a pattern signal having a short period. 
The foregoing is applied to color-separated image data of 
each color. Preferably, the image data is divided, in 
accordance with color, into predetermined areas having 
the same or a different number of pixels, or into 
predetermined areas having a planar phase which differs 
for each color, and a screen angle is applied thereto.

Title: Method of enhancing the curing of a photocurable dental restorative material
IPC: A61C5/00
Filed: 1989-11-22
Abstract: Photocurable restorative materials for making 
dental restorations usually are highly filled with fillers 
such as amorphous silica, quartz or glass powder having 
limited translucency to curing radiation. Thus the 
underside of the restoration may not become adequately 
photocured. Better curing at the underside is achieved by 
applying a coating of fluorescent or reflective material 
beneath the restorative material. When exposing the 
restorative material to radiant curing energy, the 
resulting fluorescence or reflectance by the coating 
enhances the degree of cure of the underside of the 
restoration.
